Am i trippin? my 20lb tank is still not empty and its been 3 weeks.... or am i missing something? the little ball still floats when it turns on....i just assumed that when the ball no longer floats is when its empty?
somebody tell me?????
Do you have a little pressure gauge on your regulator?
Look at the pressure gauge dial on your regulator. When it is all the way down your tank is empty.
You can also watch the dial and estimate when you will need a refill.
The fact is without some way of testing the CO2 PPM all you are doing is guessing.
A CO2 syringe is a cheap way to dial in your room. It took me 6 cartridges to get my room dialed in but I could of used 10. Those little tubes are expensive though!
Your really can't beat a controller though. You would be surprised how much the number on the CO2 monitor changes.
With my controller I can set my regulator to 10 and fill my room up with CO2 very fast. The controller can handle it no problem because it's sampling the air a few times a second.
When you unplug the sensor you have to wait 20min. for it to recalibrate itself. I move it by the window, near fresh air when I calibrate it.
One time I forgot about it and my lights and CO2 came on. The CO2 kept running full blast for about 20 minutes before I realized the lights where on.
I put the monitor in the room and it read over 3000PPM! I started getting dizzy so I got the hell out of there quick. I turned on the vent fan and closed the door.
I felt weird for about 10 minutes and ended up with a head ache. Lesson learned!
I could fill a book with all my fuck ups!
